this is very easy - take middleware service programs as CGIDEV2, HTTPAPI or
powerEXT. They all have a lot of subprocedures that shares global variables

the service program and general storage allocations otherwise they could
not run.

Additinal note:
global data and coupling procedures by global data is not bad design!

Hi Dieter,
This surprises me, which means I probably do not understand what you

subprocedures with global variables?
